GREASE-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 735,191, dated August4., 1903. Application filed March 7, 1903. Serial No.146,623. on model.)

To aZZ whom it may conce ve.-

Be it known that I, RUDOLF ALLERT, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inGrease-Sepw rators, of which the following is a specification.

My invention relates to separators for removing oil or grease fromfluids, such as exhaust-steam in which they are carried in suspension,and has for its object to provide improved means whereby to accomplishthis purpose by bringing the grease-laden fiuid into contact with platesof porous material and then draining the porous material of the absorbedoleaginous substances, whereby fresh surfaces are constantly presentedto the action of the passing fluid.

The subject-matter of this application, of which the invention consists,is an apparatus by means of which the object is accomplished, saidapparatus consisting of a separator which is, in effect, a steam-chamberprovided with plates of porous material forming parts of the walls ofdrainage-chambers and means for draining the porous material anddrainagechambers of the absorbed oil or grease, all as hereinafter fullydescribed and afterward specifically claimed.

The single figure in the drawing represents a separator embodying myinvention in central longitudinal section.

Referring to the drawing by letters, a is a chamber, made of anysuitable size and material and provided with a suitable steam-inlet pipeI) and outlet-pipe 0, each pipe being controlled by valves, as at (Z (1.Within the chamber are arranged one or more plates, as at 6, made ofporous material, such as earthenware or baked clay, which are supportedthe outer air.

age-chamber itself, which in this instance is conically shaped andconverges toward the bottom to the pipe f and is steam-tight exceptthrough the porous plate.

The operation of my device is as follows: The grease-laden steam is letinto the cham ber a, through the pipe 1), its valve being open for thatpurpose. The outlet-pipe c is closed and the valve is of the-side-trackpipe j is open. This draws a current of steam through the apparatus forheating the porous material, and thus preventing the subsequentcondensation of moisture thereon. After this operation has continueduntil the plates are sufficiently heated the valve is closed and thevalve of the outlet-pipe and the valves h of the drainage-pipesareopened. The drainage-x pipes, it will be observed, communicate withside of the bathe-plates will be lower on this account than that on theupper side, against which the steam impinges. This difierence inpressure insures the constant passage of the absorbed oil through thebaffie-plates. If, however, this difierence in pressure should not besufficient, the pipe may be connected with a vacuurnpump or similarmeans for lessening the pressure within the drainagechambers. The greaseor oil deposited on the plates is absorbed thereby, is forced throughthe plates by the difierences of pressure, collects within thedrainage-chamber, and is subsequently removed through the pipes f. Inits passage through the porous material the oil is filtered and purifiedand can again be used for many purposes, the operation of the separatorthus accomplishing the manifold result of clearing the exhaust-steam ofoily substances and purifying and saving such oily substances, whichmight otherwise be wasted.

In the special construction'herein shown I have illustrated thesteam-chamber separated into a plurality of compartments Z, in each ofwhich is a drainage-chamber g, the several compartments being separatedby partitions or diaphragms m on, having openings n 'n affordingcommunication between the compartments, the drainage-pipes f leading toa pipe 0, which leads to any suitable receptacle. I do not care to limitmyself specifically to The pressure on the reverse the use of a porousmateriahlike earthenware. Any material having similar properties-as, forinstance, charcoal, coke, asbestos, felt, &c.may be employed, withresults depending upon the efficiency of the particular absorbing mediumused.

This device is very efificient and takes out practically all of the oilfrom exhaust-steam and may be used for the removal of oily material fromammonia or other fluid with equal success. .7

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. In a grease-separator for exhaust-steam and the like, the combinationwith a steamehamber, an outlet-pipe, an inlet-pipe and a drainage-pipe,of a drainage-chamber inside of the steam-chamber having an open top andotherwise steam tight, and communicating with the drainage-pipe, and aporous plate closing the top of the drainage-chamber, substantially asdescribed.

2. In a grease-separator for exhaust-steam and the like, the combinationwith the steamchamber, an outlet-pipe, an inlet-pipe, and adrainage-pipe, of a plurality of diaphragms dividing the chamber into anumber of compartments and having openings to afford communicationbetween the compartments, a drainage-chamber in each compartment havingan open top but otherwise steam-tight and communicating with thedrainage-pipe, and a porous plate closing the top of eachdrainage-chamber,snbstantially as described.

Witness my hand this 5th day of March, 1903, at Philadelphia and Stateof Pennsyl- Vania.
